ICE-CUTTING MACHINE.

Specification of Letters Patent.

Application filed July 13. 1909.

My invention relates to new amt useful improvements in ice cutting machines and my object is to provide a device'that may be readily transported from place to place, in pursuit of the obje ts for which it is constructed and a further object is to provide. a device that may be regulated according to the depth of the cut. desired.

still further object to provide. a device that will be simple and economical in construction and etl'ective in operation.

Referring to the drawings which form part of, this application. Figure l is a side elevation of my machine. thesaw nearest the observer and bar 10 having been removed. Fig. 2 is a top plan view of the machine.

'Corresponding parts throughout the several views are designated by similar reference characters.

In carrying out my invention. l indicates an engine of any preferred type, but for convenience is here shown as a gas engine, mounted upon cross bars 3 and thereon by means of bolts 3, 3 being mounted on the forward runners l: which permit of the device beingmoved upon ice. The tly wheel of the engine 1 has mounted thereon a pulley 5 and power from the engine issuppliedtothe machine through the medium of a belt (3 mounted on said pulley 5 at one end and passed around a second pulley 7 mounted on the shaft 8, said secured said cross bars Patented Mar. 29, 19319.

standard 12 are the laterally extending braces 14 secured at the ends. opposite those secured to said standard. to a second standard 15 secured at its base to an additional cross bar 13 by; means of the traces 15'. ()n the top of the standard 1L is mounted the horizontal beam 16 to which is secured about centrally the vertically extending and substantially V-shaped keeper to. through which i passed and pivotally secured thereto a lifting bar 17.

ing bar 1? is pivotally secured a cooperating bar in. said eot'iperating bar being in turn pivoted to the extension l'ttot a subtautially inverted T-shaped cross bar 520, the head ol which is secured to the parallel bars and 1t) and countersunk therein. Secured to said standard and extending upwardly there from and thence downwardly along one of its sides, is the keeper 21, through which the free end of said lifting bar 1? extends. saidkeeper 21- having the registering openings 22 therein, whereby when said lifting bar is pushed downwardly, the pivoted parallel bars 10 and it) will be raised upwardly carrying the saws therewith. and a pin inserted in said registering openings 22 above the lifting bar 17 would be adapted to hold the saws in the raised position. if so desired. Secured to the upper portion of said standard 15, is a hook, from which is suspended a yielding spring it, the opposite end of which engages one end of an approximately L-shaped member 25. said L-shaped member being pivoted about centrally to the standard 15, and

shaft being mounted in the bearings J, which are secured to the rear ends of a pair of v parallel bars 10 and 1t) ptvot'ally mounted .betweenthe rear runners l.

Said parallel bars are pivoted between said rear runners 4' by means ot cross bar l1 and one or more circular saws are adapted to be mounted on said shaft 8, whereby it will be seen that when power is applied to the pulley 7, from the engine 1. said saws I! will llt operated.

The standard l2 is secured to a cross bar lf} mounted between the rear' runners c, and secured to the upper portion of Said mounted in the opposite end thereof is a shaft it; carrying the belt. tightener 27, the

purpose of which is obvious.

It will be seen that applicant has provided a machine that. may be readily transported on the ice from place to place, and

that can be easily regulated according to the depth of the cut desired, and it will still further be seen that a machine has been provided that although simple and novel in construction, is etl'ective in ope 'ation.

'hat I claim is:

in an ice cutting machine, the combination with a pair of forward and rear runners, an engine mounted on cross bars be tween said for 'ard runners, a pair of vertical standards mounted between said runners, a pair ol parallel bars pivotall mounted between said rear runners, a shit t To one end of said lift-' mounted between said bars and carrying one 0 lever extends and registering openings in or more circular saws, means for cooperation raised or lowered through means of said lever, said lever can be held in any desired position.

In testimony whereof I have signedmy 15 name to this specification in the presence of two subscribing Witnesses.

between said engine and said saws, and a lever fulcruined on a keeper carried above the rear vertical standard with additional leverage secured to one end of said lever and to said parallel bars, the forward vertical standard having a metallic keeper secured and extending parallel to one of its sides through which the opposite end of said Witnesses Geo.
